ToaZZ whom it may concern:

Be it known that I, GnonenDUBAY; a cit1-.

zen of one United States residing'at Barre,

in thelcounty of Washington andf'State" of l' erinont, have invented certain new and useful Improvementsvin Holding De vices for lvlachine-Tools; and I do hereby declarethe following to be aifull,"clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to'make andnsethe same. J r l his invention relates toholding devices for machine. tools ofthat character adapted to be used in connection with lathes to readily accommodate and hold difierent forms and sizes of the turning, forming and bor ingtools, commonly used therewith.

i The chief object of'my invention is to provide essentially .-simple and eifective means torholdingthe varieties of cutting tools? f A further objectof my invention isto provide means for holding square headed bolts when my attachment'is' used in 'conneca tion with a .threac'lingi'machine. U

A still f urthe'zr' object Jis to provide means c 7 position when such is ClGSll'QClCObQ used. c r

I make use ofajfixed. jawor stockattachedto a bed plate and adapted tobe usedin :con nection with a movable jaw ordstock slidingly'adjustable on said bed plate; The inner or meeting faceslof these jawsare provided with means to be hereinafter described for :holdingithe various desirable tion to reside;

A practical embodimentof this invention "is represented in theacco npanying draw? ings forming a part otthisspecification, in

which similar 'nunieralsv of reference indicate corresponding parts throughout all the views." Figure 1 is a perspective View of my invention as an entirety. the, same beingshown detached from the '1athe.- Fig.2 is ab sectional view of the arts shown in Fi .v 1. i b

Adjacent both tel-mi nals of each aw, are preferably formed the I grooves or recesses intended to hold, the 7 various tools or bolts. ,The, forward groove i orrecess 15 as shown in Fig. -l..is arcuate,

running as it does from the upper face of each ]tiW..lI1tO the longitudinal groove 1%. This is designed'to fit the U-shaped chuck bolt'ofa steam drill of the ordinary con struction. The rearward recess is arugula rly shaped as shown at-"15- in order to accom- ,modate the square; head of a boltwnen my attachment is used as an-adjunctto a threading machine.

The handle screw 16 extends through the center of the fixedjaw 7 and at right angles angularly turned portion 21 and a suitable extremity of this hand'lefscrew 16 is seated handle 22 connected thereto.

When so used the handle screw is withdrawn fromits aperture in the 7 'andthe square head ofth'e' bolt is inserted V jjtwo jaws in such way that it may be clamped therein "by means of the setscrewfl'i" with if the shanki oi the bolt resting inthe grooves inthe corresponding angularrecessesof the '14 and projectingfout beyond.

A still further application of my holding device for lathes rendered possible by the recesses 15 of the which'renders this invention adaptable for the use of a steam drill. The drill may be positioned in the groove 14 in the regular manner so that the 1 ducts of the'steam drill lie within the recesses 15 and extend upwardly tomake suitable connections withthe steam' pipes; It is "obvious that the construction of the top plate 8' having the'cut away portion 8 ren ders this a desirable and possible use-for the holding device.-
